masser i# FORM SUPPORT.

Application led January 7,1922. Serial No. 527,595."

To all whomz't may concern.'

Be it known that I, VILLIAM E. WHITE, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new 'and useful Improvements in a Form Support, of which the Yfollowing, isa specification.

My invention relates to` supporting devices for forms and particularly to a novel construction adapted for` easy manipulation without the use o1c special tools. g

In the device of my invention I provide hangers which may constitute the depending legs of a stirrup and mount a-sleeve 0r clasp for vertical sliding movement on each of the legs. A bracket adapted to retain aV `form pan in a desired location is held in interlocked relation to the hanger and sleeve by gravity action of the sleeve. To disengage the bracket andv permit the loweringof the' form pans it is only necessary to movel the sleeve upwardly to the extent of disengaging it from a notch in the bracket, whereupon the bracket is separated by its own weight. A construction 'such as described is advantageous in that the manner oi:` use is simplified. There are no loose parts which may become separated with the exception of the bracket which constitutes but a small part of the total cost of the assembly.

The invention will be more readily understood by reference to the accompanying drawings, wherein,

nig. 1 is a sectional view through a molded floor and beam showing the iorms held .in place by the device of my invention;

Fig. 2 is a side elevation partly in section on the line 2 2 of Fig. 1; i

F ig. 3 is an enlarged perspective view of the moving parts of my invention;

Fig. 4 is an enlarged side view with a part ot the sleeve broken away, and,

Fig. 5 is a sectional view upon the line .5*5 of Fig. 4..

In the drawings it will be seen that the purpose of my invention is to provide means for supporting form pans 10, of well known construction. These are-'utilized to mold a door slab 11, and a beam 12, The bottom oit the beam is outlined by a plank 13. This rests upon joists 14E, which serve to carry the weight of the molded Concrete, Interposed between the plank and the joist is a member in the form of a stirrup having an upper plate 15 and depending legs, one on each side of the joist. These legs are shown as integrally joined to the plate 15,.,butas inl r i dicated in a co-pendi'ng applicatiomSerial No. 524,445, iled Dec. 23, 1921, theymay be formed separately and be adapted fordis` engagement.' l

The' legsfare `shaped toprovide an inter-l mediate portion` 16, ladapted to lie against the'joist 14, thisA portion having a plurality of vertically spaced `apart apertures 17. The margins 18 of the legs or hangers are laterally deliected to lie` in ajplaneoutside 1 oi' the plane of the central portion 16 and to.

constitute guides for a sleeveor clasp 19,'`

the inturnedvkedges 20 ofvwhich extend around the flanges 18. ,This sleeve acts 'as a lock for a bracket 21, the innerend of which is provided with upper and lower projections 22, 23, respectively, adapted to enter two of the apertures` 17 in the hanger.

In the upper edge of the brackets near `the v upper projection 22, I providea vnotch v24.

The Outer end of the bracket may have a lug 25, for an obvious purpose.

The sleeve has an elongated aperture 26 therein, of a length slightlygreater than the over-all vertical depths of the bracket, The bracket is adapted to be inserted in the aperture in such'position that the projections 22,'

23, therein occupy two ofthe recesses in the hanger.4 rThereupon the ,sleeve` or locking member is permitted to drop by gravity and i, to engage the notch 24m the Vupper edge of the bracket. -In this position the bracket is securelyheld against displacement, the weight sustained by t-he bracket being held by the combined resistance of. the interlock between the sleeve and bracket and the v abutment of the lower projection on the bottom' of its cooperating recess.

To displace the braoket'it is only necessary to apply force to the locking member to move the same upwardly, whereupon the bracket will rotate about the lower projection and fall out of its position.

Obviously the device is capable of, much modication and I do lnot wish to be limited exceptv as indicated inthe appended claims.

I claimt ,I

1. In a form supporting device, the com'- bination of means adapted to rest upon a supporting joist and provided with depending notched legs, a sleeveguided and vertically reciproeable on a leg, and a bracket having a portion adapted toy cooperate with said sleeve and with a notch in said leg yso in forni supporting device, the corn-4 bination oi a stirrnp having depending apertured lees, the marginal edges ot which are adapted o act as guides, a sleeve vertically slidable thereon, and a bracket adapted to cooperate ivith the sleeve and provided with a projection adapted to enter an aperture in said leg whereby the bracket is disengageably interloclred With the leg of a stirrup. Y i

3. ln a'torin supporting device, the cornbination ot a stirrup having depending apertured legs, the marginal edges of which are adapted to act as guides, a sleeve vertically slidable thereon, and a bracket adapted to cooperate with the sleeve and provided with a projection adapted to enter an aperture in said leg whereby the bracket is held in interloclred relation to the leg by the gravity action of the sleeve. e. in a device of the class described, the combination or a support adapted to rest upon a joist and provided with dependin recessed legs, a sleeve guided upon each leg and provided with an aperture in alignment with the recesses in said leg, and bracket adapted to project'through the aperture in the sleeve and to engage a recess in said leg and to be held in interloclred relation with the leg by said sleeve.

5. ln a device o' the class described, the combination ot a support adapted to rest npon a joist and provided with depending recessed legs, fr sleeve guided upon each leg and provided with an aperture in alignment with the recesses in said leg, a bracket having a projection upon its inner end adapted to cooperate With recess in said leg and notch o-n its upper surface, said bracket being adapted to project into the aperture in the sleeve in such position that the projection therein engages a recess in the leg and the notch in the upper surface thereof cooperates with the sleeve whereby the parts are held in inter-locked relation by gravity action ot the sleeve.

6. ln a forni supporting device, the coinbination of a stirrup having notched depending portions, the marginal edges of the depending portions being laterally deflected to lie in a plane outside of the plane in the central portion thereby forming guides, a sleeve slidable 0n said guides7 said sleeve being provided with an elongated aperture opposite the recesses in said depending portion, and a bracket having a projection adapted to enter a recess in said depending portion. and with a notch adapted to be. engaged by the portion of the sleeve at the upper end oi said elongated aperture whereby the bracket'is held in adjusted position by gravity action of the sleeve and being adapted to be released by upward sliding movement or the sleeve relative to the bracket.

7. ln a device ot the class described, the combination of a depending leg notches therein, a clasp slidable on the rnar; ginal edges of the leg a guide, and a bracket having a portion adapted to enter one of the recesses in said leg and being notched on its upper edge for engagement With said clasp, the clasp being held in enI gagenient with the bracket by gravity action.

8. ln a. .torni support, the combination ot means including Va depending leg having ver ally spacedA recesses, a separable bracket having a pair of vertically spaced projections adapted to engage two ot said recesses, and a locking rneinber slidable on said leg and adapted to engage the bracket by gravity near its upper projection and to prevent the separation of the bracket 'from the leg by rotation about its lower projection. y j
